The study of small, regulatory RNAs (sRNA) that act by base-pairing with target RNAs in bacteria has been steadily advancing, particularly with the availability of more and more transcriptome and RNA-RNA interactome datasets. While the characterization of multiple sRNAs has helped to elucidate their mechanisms of action, these studies also are providing insights into protein function, control of metabolic flux, and connections between metabolic pathways as we will discuss here. In describing several examples of the metabolic insights gained, we will summarize the different types of base-pairing sRNAs including mRNA-derived sRNAs, sponge RNAs, RNA mimics, and dual-function RNAs as well as suggest how information about sRNAs could be exploited in the future.

Esophageal cancer is a common and often deadly malignancy, with treatment success depending largely on the stage at the time of diagnosis. Recently, studies have examined the role of non-coding RNAs in esophageal cancer pathogenesis, prognosis and therapy. This perspective specifically examines interactions long non-coding RNAs have with other RNA molecules in various facets of esophageal cancer.

This study aimed to identify shared gene expression related to circadian rhythm disruption in polycystic ovary syndrome (PCOS) and non-alcoholic fatty liver disease (NAFLD) to discover common diagnostic biomarkers. Visceral fat RNA samples were collected from 12 PCOS and 14 non-PCOS patients, a sample size representing the clinical situation and sufficient to capture PCOS gene expression profiles. Along with liver transcriptome profiles from NAFLD patients, these data were analyzed to identify crosstalk circadian rhythm-related genes (CRRGs) between the diseases.

Cells are subjected to dynamic mechanical environments which impart forces and induce cellular responses. In age-related conditions like pulmonary fibrosis, there is both an increase in tissue stiffness and an accumulation of senescent cells. While senescent cells produce a senescence-associated secretory phenotype (SASP), the impact of physical stimuli on both cellular senescence and the SASP is not well understood.

Post-traumatic epilepsy (PTE) is a debilitating chronic outcome of traumatic brain injury (TBI). Although FTO has been reported as a possible intervention target of TBI, its precise roles in the PTE remain incompletely understood. Here we used mild or serious mice TBI model to probe the role and molecular mechanism of FTO in PTE.

Globally, the incidence and death rates associated with cancer persist in rising, despite considerable advancements in cancer therapy. Although some malignancies are manageable by a mix of chemotherapy, surgery, radiation, and targeted therapy, most malignant tumors either exhibit poor responsiveness to early identification or endure post-treatment survival. The prognosis for prostate cancer (PCa) is unfavorable since it is a perilous and lethal malignancy.
